I'm really sorry but I've no idea about what's happening with wind power...
1) when you use that power can you ear the wind sound?
2) does the hourglass disappear after some seconds? Or you have to restart the game?
Thanks for the other bugs report.
1) Yes, I can hear the wind sound and see the tornado animation wandering through the screen until it leaves. Now that you mentioned the sounds: Always I wondered why do I hear the sound of the horse as well, even if I am 1 or 2 scenarios away from it - to say: the horse is not in the actual screen!
2) No, the hourglass does not disappear! I cant do anything else, except leaving the game by pressing ALT+F4. Now I figured out something strange: The windpower seems to works fine to the north & south -game cursor comes back and no horse sound-, but seems to crash all the time to the west & east directions -horse sound and hourglass wont disappear.
So I can hope to need the wind only in north/south directions?
